Abstract (en)

[origin: WO2013054019A1] The invention relates to a method for controlling the movement, on the ground, of a device (100) having at least two legs (120), including: a step of obtaining (300, 400, 800) current values (sigma) of variables pertaining to the kinematic state of the device; a step of optimising (320, 420, 820), under constraints (1500, 1900), a movement command (v) for the device, while taking into account said current values and a set value of the movement of the device, said optimisation being carried out by modelling a movement of the device between a current state (t1) and a second state (t2), the device resting, during said movement, on at least a first leg and then, from an instant of changing the centre of pressure on the ground (tp), on at least a second leg; and a step of applying (330, 430, 830) said movement command, characterised in that said optimisation is carried out under the hypothesis that the gravitational potential energy of the device in the second state (t2) is at a time-based local maximum.
